I've set a virtual directory in /etc/apache2/sites-available/default like so:
Alias /lynx/ "/home/srv1100/" <Directory "/home/srv1100/"> Options Indexes MultiViews FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory>
every file is accessible when I write http://127.0.0.1/lynx/... I want that only files, which their extension is NOT "bsp" or "nav" and will be accessible. I can't put them in other directory.
